It has been almost 4 years since the last album (A&C) was added into the game, and since then, a ton more collections and cards have been added that don’t fit the albums that they’re in. Initially, the Our World album was designed to home all of these collections, but as a result of it being scrapped, collections such as Natural Monuments and Super Structures have all grown to a scale where it doesn’t make much sense to keep them in their current albums. Most of these collections are currently categorized as Science, which is quickly becoming one of the largest albums in the game, even though many of these cards do not fit. Without the Our Worlds collection, there is a ton of collections that can’t be properly explored due to the inability to categorize them in the current 7 albums. However, there is now enough cards in the game that could be categorized as “Our World” to finally add it into the game without having to add hundreds of cards to fill out the collection (It would still take a lot of work).
Collections that should be moved:
Walking the World
Wonders of Construction
Majestic Mountains
Natural Monuments
Super Structures
Volcanoes
Collections that could potentially be moved:
Raging Rivers
Riding the Waves
Awesome Aviation
Climate Change
Forces of Nature
On Track!
The creation of this album would open the opportunity to create collections highlighting the world’s forests, caves, deserts, biomes, bridges, transportation, cities, beaches, waterfalls, geography, etc. I hope you can also see the potential that adding this album would bring to the game
